In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthetic methods and reactions. 63. Pyridinium poly(hydrogen fluoride) (30% pyridine-70% hydrogen fluoride): a convenient reagent for organic fluorination reactions, published in 1979, which mentions a compound: 616-14-8, mainly applied to fluorination pyridinium polyhydrogen fluoride; diazotization fluorination; safety pyridinium polyhydrogen fluoride, Application In Synthesis of 1-Iodo-2-methylbutane.

Pyridinium polyhydrogen fluoride (30% pyridine-70% HF) reagent, a stabilized, less-volatile form of HF, is a convenient and effective fluorinating agent. Fluorination, halofluorination, nitrofluorination, and hydrofluorination of olefins were achieved using the reagent. The in situ diazotization and subsequent fluorinative dediazonization of α-amino acids, aminoarenes, and carbamates yielded α-fluorocarboxylic acids, aryl fluorides, and fluoroformates, resp. Geminal dihalides and α-halo ketones were treated with HgO in pyridinium polyhydrogen fluoride to form geminal difluorides and α-fluoro ketones. Solutions of alkali halides in pyridinium polyhydrogen fluoride were also effective halogenating agents for aminoarenes, via in situ diazotization and subsequent nucleophilic dediazonization by the corresponding halides, as well as for alcs., via SN2 displacement reactions. Diazo ketones and diazoalkanes also reacted smoothly with halide ions in pyridinium polyhydrogen fluoride solution to give the corresponding geminally halofluorinated compounds Proper precautions must be observed in using pyridinium polyhydrogen fluoride.

Considering the nonideal metabolic stability of the difluoro-biphenyl-diarylpyrimidine lead compound I, a series of novel alkylated difluoro-biphenyl-diarylpyrimidines were designed and synthesized based on their structure. Introducing alkyl or substituted alkyl groups on the linker region to block the potential metabolic sensitive sites generated 22 derivatives Among them, compound II with an N-Me group displayed excellent anti-HIV-1 activity and selectivity. The Me group was hopped to the central pyrimidine to occupy the small linker region and maintain the water-mediated hydrogen bond observed in the binding of compound I with RT. The resulting compound III exhibited an improved anti-HIV-1 activity, much lower cytotoxicity, and nanomolar activity toward multiple mutants. In addition, III has a better stability in human liver microsomes than I. Moreover, no apparent in vivo acute toxicity was observed in III-treated female, especially pregnant mice. This series of alkylated compounds with highly potency and safety represent a promising lead template for future discovery.

Rotatory dispersion curves of halides of the type HMeRC(CH2)nX (X = Cl, Br, I; R = alkyl group; n = 0, 1, 2 or 3) are analyzed in the visible and the ultraviolet regions. The 3 halogen atoms function similarly with respect to the character of this curve in compounds of identical structure. A periodicity in the sign of some of the partial contributions of the halogen atom occurs with increase in n. The course of the rotatory dispersion when n = 1 is anomalous. An attempt is made to apply results when n > 0 to the sign of rotation for compounds where n = 0. When X = COOH, CHO, CN, CHMe2, etc., no complete analogy exists between this group and the group where X is a halogen. [M]D25 maximum (homogeneous) is given for the 16 compounds where X = Br, n = 1, 2, 3, 4, and R = Et, Pr, Bu, pentyl, and for the compound HMeEtC(CH2)5Br. Absorption spectra are given for λ 2100-3300 for 5 iodides. Rotatory dispersion curves are given for the compounds HMeEtCCH2I, HMe(C6H13)CCH2I, HMeEtCCH2Br and HMeEtCCH2Cl. [M]D25 maximum, nD25, d425 (vacuum) and rotatory dispersions (numerical) are given for several other compounds in this series. Differences between the interpretation of the dispersions of the iodides given by the authors (C. A. 27, 951) and that given by Kuhn (C. A. 29, 7159.1) are due to substantial differences between their exptl. data.

Alkyl halides are an important source of halogens in the atm. In the case of alkyl iodides, relative kinetic studies of their OH reactions in photoreactors are complicated by fast reactions with the O(3P) atoms generated by the photochem. OH radical sources. In the present study, the relative kinetic technique was applied in large and small photoreactors to measure rate coefficients for the reaction of O(3P) atoms with a series of alkyl iodides at room temperature and atm. pressure. The products formed in N2 were also investigated. Alkenes and HOI are the major products of the reactions and the alkene was quantified for the majority of the alkyl iodides studied.
